There are two, GetWindowText() and GetDlgItemText(). You'll probably find the second one easier. You pass it the handle to the edit's parent window (which is usually a dialog, thus the name of the API) and the ID of the edit control itself, along with a character buffer. The API stores the text in the buffer.

It's a humor site where you give it two key words/phrases, and it Googles for them both and reports the # of hits for each one. The one with more hits wins.
This particular fight was inspired by someone saying Britney Spears was hotter than Erica Weichers, which is of course utter bollocks, but the Web doesn't seem to agree.

Who would SAY such a thing ? She's pretty skanky though. My grandmother (1 190 000 results) beats her too.

That's really cool. Way too many people seem to start with Windows programming without learning any C++ first.
If you're using VC6 then you hit CTRL-W to bring up the class wizard, and in the second tab, you can set variables for a class. There are two options, you can create a variable which holds a string or a number, or a control variable. If you use the former, you end up with a CString ( or an int, etc ) that holds your value. You call UpdateData(FALSE); to populate the variable, and UpdateData(TRUE); to put the variables value into the control. I prefer to create a control, which also means you can hide/move/change it, and then to get the value out you do something like this:
CString sEdit;
m_MyEdit.GetWindowText(sEdit);
And SetWindowText puts the value into the control from the CString.

Now imagine, just for one second, what would have happened if Microsoft had decided to add just a few extra operators to the CEdit class:
CEdit& operator=(const CString& strText);
CEdit& operator=(int nText);
CEdit& operator=(double dText);
operator CString() const;
operator int() const;
operator double() const;
Then we could do things like:
m_editCtrl = "This value";
m_editCtrl = 123;
functionWhichTakesACStringParam(m_editCtrl);
int nValue = m_editCtrl + 10;
Oh well, we can only dream of what could have been. It's just amazing how much easier VB developers could have picked VC++ if Microsoft had really exploited the power of C++ inside MFC.

Alvaro

I'd settle for GetWindowText returning the string so you could concatenate operations. What you're suggesting would be so cool as to be unheard of.....

Ahhh, the power of C++. This can easily be accomplished with a simple subclass.
CEditEx& CEditEx::operator =(const CString& str)
{
SetWindowText(str);
return *this;
}
CEditEx& CEditEx::operator =(int nText)
{
CString str;
str.Format(_T("%d"), nText);
SetWindowText(str);
return *this;
}
CEditEx& CEditEx::operator =(double dText)
{
CString str;
str.Format(_T("%0.6f"), dText);
SetWindowText(str);
return *this;
}
CEditEx::operator int() const
{
CString str;
GetWindowText(str);
TCHAR *temp;
return (_tcstol(str, &temp, 10));
}
CEditEx::operator double() const
{
CString str;
GetWindowText(str);
TCHAR *temp;
return (_tcstod(str, &temp));
}
CEditEx::operator CString() const
{
CString str;
GetWindowText(str);
return str;
}I am sure this could be improved (error checking etc.) but you get the idea.

No I haven't. I didn't actually think of this until Alvaro and Christian said how cool it would be. And then I thought "why not? sounds simple enough". Maybe Alvaro would be a better candidate to write an article as it was his idea originally.

But thats the point: Microsoft did fail to perform even so basic things.
Instead they devised such useless crap as DDX/DDV.

 hi laurent..
thanks for ur reply..i found the link on code project's ATL page... hope this will help me out at last...

Starting with an example situation.....some of you might know that when you create an ATL COM project using the VisualStudio new project wizard, the newly created resource (*.rc) file will contain a TEXTINCLUDE directive that includes the project's type library (*.tlb generated from MIDL compiling the *.idl file) INTO the resulting binary (EXE or DLL).
Now, my question involves the case when 2 or MORE type libraries are included in this fashion into the resulting binary file.
If you are using the API function 'LoadTypeLib', you can specify which of the included type libraries you want like this:
LoadTypeLib("C:\\MyServer.dll", ...) for the first, (or also "...\\1")<br />
LoadTypeLib("C:\\MyServer.dll\\2", ...) for the second,<br />
LoadTypeLib("C:\\MyServer.dll\\3", ...) for the third, and so on<br />
 HOW CAN THIS BE DONE WITH THE '#import' directive?????????????
I can't believe microsoft would ignore the capability of generating com interface wrapper classes for secondary type libraries.
Is there an extractor tool that I'm unaware of that removes type libraries from 'dll's or 'exe's and saves them as 'tlb's.
I don't want to START with OleView, THEN find object, THEN copy Idl definition, (THEN find next object, THEN copy idl definition,...) THEN Midl compile, THEN FINALLY #import (besides this process is incomplete unless you ALREADY have a list of ALL the COM class objects that exist in the secondary type library).
HEEEEEEEEEEELLLLLP, i'm dieing here 
thanks,
nebbish

VC can do that. Open the EXE/DLL but pick Resources in the Open as combobox. From the resource editor you can save any resource as binary data (just name the file something.tlb and you're set).

hi everyone,
what message do you use for multiple selection in a list control? when i said multiple selection, i meant when you hold the ctrl key on the keyboard and click on multiple entries in the list control that you want to select.
thanks in advance.

LVN_ITEMCHANGING is sent before an item's state changes (so you can reject the change if you want). LVN_ITEMCHANGED is sent after the state changes. There's also  LVN_MARQUEEBEGIN for when the user drags a rectangle in the list to select items.

I need to move just a single control in my view to keep it centered on the screen. I have tried overriding the OnHScroll() and adding code to MoveWindow() for my control to move it. I can't seem to keep it visible.
Here is the code sample:
<br />
void CMYView::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar *pScrollBar)<br />
{<br />
CRect r;<br />
int nNewCalPos;<br />
<br />
if(pScrollBar) return;
<br />
switch(nSBCode)<br />
{<br />
case SB_LINERIGHT:<br />
m_nHPos += 204;<br />
if(m_nHPos > m_nMaxRange)<br />
{<br />
m_nHPos = m_nMaxRange;<br />
nNewCalPos = m_nMaxRange - 204;<br />
}<br />
break;<br />
case SB_LINELEFT:<br />
m_nHPos -= 204;<br />
if(m_nHPos < 0)<br />
{<br />
m_nHPos = 0;<br />
nNewCalPos = 150;<br />
}<br />
break;<br />
}<br />
<br />
CScrollView::OnHScroll(nSBCode, nPos, pScrollBar);<br />
<br />
m_cCalanderCtrl.GetMinReqRect(&r);<br />
m_cCalanderCtrl.MoveWindow(nNewCalPos, 0, ((r.right * 4) + 20), r.bottom, TRUE);<br />
}<br />
Any ideas?
Thanks,
-Eric

Hi --
Suppose I have a data set like:
1 2 3 4
4 5 6 9
1 5 9 6
in an external file. How do I read this external data set into a 3 by 4 array in visual c++.net. I do not have SQLClient.. Could I do this with dynamic arrays?
Thanks

Yes, you don't need SQL Server, in fact it would do nothing for you. Read my articles on iostreams and std::vector.
